Congenitally corrected transposition of the great arteries with severely stenotic bicuspid aortic valve in an adult: a case report.

Congenitally corrected transposition of the great arteries (CCTGA) is a rare disease accounting for 0.5-1.4% of patients with congenital heart disease. In this congenital cardiopathy, the left atrium is connected to the right ventricle, from which the aorta stems. We present a case of an adult with CCTGA associated with aortic stenosis and bicuspid aortic valve-an association not yet described to our knowledge.

Does cirrhotic cardiomyopathy exist? 50 years of uncertainty.

Subtle abnormalities of cardiac structure or function are often identified in patients with liver cirrhosis and have been termed cirrhotic cardiomyopathy. However, in the absence of a precise definition, its diagnosis remains a challenge. Cardiac dysfunction in patients with cirrhosis can often be attributed to concomitant diseases such as hypertension, ischaemic heart disease or excess alcohol consumption in many patients. Further research is required to identify the existence, origin and importance of abnormal cardiac function due specifically to liver disease. Cardiac dysfunction may be masked by treatments given to cirrhotic patients, such as mineral-corticoid receptor antagonists, or by co-existing conditions, such as anaemia. New imaging tests or plasma biomarkers might be able to detect abnormal cardiac function at an early stage of its development.

Cardiac dysfunction in cirrhosis is not associated with the severity of liver disease.

BACKGROUND: Cirrhotic cardiomiopathy is described as the presence of cardiac dysfunction in cirrhotic patients. The aim of the study was to investigate factors associated with cardiac dysfunction in cirrhotic patients. PATIENTS AND METHODS: Seventy-four cirrhotic patients and twenty-six controls performed a conventional echocardiography and Tissue Doppler Imaging (TDI) for systolic and diastolic function. Results were analyzed by using the Guidelines of American Society of Echocardiography. RESULTS: In patients with cirrhosis, left ventricular end-diastolic diameter was increased (p<0.001) , peak systolic velocities were decreased (11.3±2.7 vs 13.9±1.4cm/s; p<0.001) and left atrial volumes were increased (32.7±8.3 vs 24±8.5ml, p<0.001) as well as cardiac mass (90.6±23 vs 70.5±22g/m(2), p<0.001). Forty-seven cirrhotic patients (64%) showed diastolic dysfunction at rest: grade I in 37 and grade II in 10 patients. Systolic and/or diastolic dysfunction were not influenced by a more severe liver impairment. Diastolic dysfunction was more prevalent in patients with ascites vs those without (77% vs 56%; p=0.04). CONCLUSION: A mild diastolic dysfunction at rest is frequent in cirrhotic patients but cardiac load conditions are confounding factors in this diagnosis. We did not identify an association between severity of liver disease and cardiac dysfunction.

Subclinical anthracycline cardiotoxicity in patients with acute promyelocytic leukemia in long-term remission after the AIDA protocol.

Anthracycline chemotherapy remains a critical component of cancer treatment despite its established risk of cardiotoxicity. To investigate whether the AIDA protocol, which combines idarubicin, mitoxantrone, and all-trans retinoic acid (ATRA) for treatment of acute promyelocytic leukemia (APL) results in late cardiotoxicity, 34 APL patients in long-term remission were evaluated. The cumulative dose of idarubicin and mitoxantrone were 80 mg/m(2) and 50 mg/m(2), respectively. Median follow-up was 7 years. Segmental wall motion abnormalities (SWMAs) were detected in 11 AIDA patients who still presented with an ejection fraction (EF) within normal limits (EF 56% in the AIDA group vs 59% in the control group, P=.01). However, parameters of diastolic dysfunction were significantly impaired in the AIDA group (E/A ratio: 1.04 in the AIDA group vs 1.28 in the control group, P=.001; E/E' lateral ratio: 10.04 in the AIDA group vs 5.79 in the control group, P≤.001) as well as left atrial volume (52 mL in the AIDA group vs 35 mL in the control group, P<.001). Cardiac toxicity due to anthracycline therapy is often frequent. Changes in diastolic function are helpful in the detection of subclinical anthracycline cardiotoxicity in long-term cardiac follow-up despite a preserved systolic ventricular function.
